Given this - I think it's safe to say no one has heard of Windows Phone! (Seriously - I watch our device testers - 20k flavors of Android, including the Kindle versions, all the iOS devices, but I've never seen them handle a windows phone)

I use Solaris, Linux, and Windows machines at work. My home machine is an iMac because I do not want to have to think that hard, and the underlying operating system is a Unix variant. However, I chose to go with a Nokia Windows Phone when I upgraded my old phone. I own a Google Nexus 7 tablet, so I knew that I wanted nothing to do with Android. Even though I loath Windows 8 and 8.1 on a desktop machine, I preferred the Nokia Windows Phone to the iPhone 5.

I looked at the Windows phone during my last upgrade. The lack of adoption leaves it lacking in the app department, which hinders future adoption. I don't know how they break out of that cycle... but in the meantime, Drew is right. There probably are not enough users to warrant bothering.

I cannot win for losing. Strike one, there is no support for Windows phone. Strike two, the app is not compatible with Google Nexus 7 tablets. My Nexus 7 is running Android 4.4.3, so much for the Android 4.0+ compatibility claim.
